I have been doing this for over a year now and they can and do ask you for a paystub on occassion. No biggie for me, since I work for a participating retailer. Shipping really sucks on this, if you aren't ordering $50 games, it really isn't worth it. I just ordered 3 games and the shipping was close to $18.
